Looking for the best one knob tone control.

[ALBATROS1234]

I started with a supro spectator schematic and after changing it around a bit I got it to a good sound trouble is i would like to use a simple tone to dial in different guitars . Right now I have a 1meg vol after the 1st triode stage and another after the second before the ppowertube .I sound good but I didn't like the original circuits tone and I tried a tweed but it seems to steal a little bit of good mojo from my amps fangs. I guess I can just go timeless and get a graphic away pedal or something but was kinda hoping to put a simple treble cut or if there is something that would work well without taking that little something special about the raw tone. Any suggestions welcome

This is not a simple question - it invokes subjective & objective aspects.  Subjectively, it's a tone preference thing.  An objective factor is the amount of signal loss in the tone control circuit.


Here's a selection of one knob controls:  http://chasingtone.com/yourguitaramp/guide-to-single-knob-tone-controls/


Seemingly, the Tweed Control matches what you want: treble control with low signal loss.  But it's not working for you.  Maybe try the Vox, or simple Treble Cut


The Big Muff control works like the FMV TS using just one knob, but has more insertion loss.

Here is another site to look at.  The one knob tone stack is at least quick to assemble and experiment with.  I find the one knob tweed sounded great in a clean tone blackface style practice amp  but not so interesting in a higher power amp.

Take a look at the brilliance switch on my AC-15 amp.  It's a 6-position rotary switch that allows you to select different coupling caps for a wide variety of tones. Some people even use a 12-position switch for even more tone variety. Simple, cheap, and almost no loss like a typical tone suck circuit. See page 2 of this pdf...

Thanks guys the experimentation begins. I liked the tweed style in the previous 3 amps I built. On this one it wasn't behaving correctly. I know that the basic tweed control is supposed to be low loss but in this amp it's way to interactive. I tried to vary the cap value using multiple sizes and it either sounded like garbage or it weakened the bite of the amp to the point that it sounds significantly better in every way with just pre and post volume/gain knobs. It also seemed more interactive than the same tone circuit in the other amps I built.

The thing is I would like slightly to have a slight bit more treble overall and when I  hook up the tone in configs I know about it looses the mojo . I tried several bright caps but either it was too much chalkboard fingernails or it just sounded off in away. I will look into experiments but it dawns on me what would be ideal would be to have a rotary control that would blend in or out a frequency for instance, the 560pf when I placed it on the volume it seemed not bad but there seemed to be too must off whatever it contributed to the tone. Maybe I need to look a install a pot to blend a brite cap in as much as I want in a given circumstance. Is there any tone circuits like this in existance???

this one's pretty good

Same of Tone Control with Rotary Switch without Rotary Switch (only two cap and one pot)
